waiving of open-access fees

Authors from developing countries submitting to Acta
Crystallographica Section E may
apply for their open-access fees
to be waived. Waiver requests must be made before submission
of an article to the journal. Successful applicants will be given a
waiver voucher valid for the submission of five papers.

For the purposes of waiving of fees, the corresponding author
should be from a developing country with a small economy (with a
GDP
of less than USD 250 billion) that is in the World Bank's
low
income or lower-middle
income categories. Qualifying countries are given below.
